NIGHTkilla's ratchet 174 BPM

Have recreated a bit dirty dubstep / drumstep bass from "Flo Rida - I Cry (NIGHTkilla Dubstep Remix)" with 90% accuracy, I think... Initially it was made by Rukkus / NK / Realistik. Adapted to 174 bpm, so test with PERFs, Noise and OSCs Amp in Massive for another bpm. So, you need: Massive, SerumFX, Ozone 5, Pro-Q3. Don't know why this sound reminded me of a ratchet...
